METAL-BENDING DEVICE.

Application filed `February 26, 1923. Serial No. 621,436.

To all whom may concer-vt.'

Be it'known that I, HORACE D. PARKER, citizen of the United States of America, residing at Vickery, in the county of Dallas and tate of Texas, have invented certain new and useful Improvements in Metal- Bendin Devices, of which the following is a speci cation.

This invention relates to new and useful improvements in metal bending devices.

In building construction metal lath is extensively used and it is frequently necessary to conform this lath to variously shaped recesses, pilasters, cornices and the like. In order to support the lath steel brackets must be provided and these brackets are generally made from channel irons. In making brackets for supporting the latb for ceilings and the like, it is necessary to bend the channel upon itself and also to make very acute bends.

The object of my invention is to provide a portable tool which may be fastened upon a work bench and arranged sothat the channel or other bar as bent, will be swung over the bench, instead of outwardly from the bench.

A. particular object of the invention is to provide an anvil or member shaped and located with relation to the bending element, whereby a metal bar may be bent around the end of the anvil to an acute angle or into parallel relation if desired.

A construction designed to carry out the invention together with other features of the invention will be hereinafter described.

The invention will be more readily understood from a reading of the following speciiication and by reference 'to the accompanying drawings, in which an example ofthe invention is shown and wherein:

Figure 1 is a plan view of a device constructed in accordance with my invention,

Fig. 2 is a side elevation of the same, and

Fig. 3 is a cross-sectional view taken on the line 3 3 of Fig. 1.

In the drawings the numeral 10 designates a flat base which has downwardly bent feet 11 at its front corner and a similar foot 12 at the center of its rear end. The base is thus elevated from the bench or board upon which it is fastened, the feet. having eyes 13 for receiving screws or other fastenings.

A gauge and guide bracket 14 extends longitudinally of the base and has a laterally projecting foot 15 provided with a slot 16 extending transversely of the base. A bolt 17 passes thru the slot and is fastened in the base.A Relatively on each side of the bolt the base has at its outer edge upturned ears 18 in which screws 19 are threaded. These screws bear against theadjacent edge of the foot 15 on each side of an extension 2O projecting between the ears 18. VBy loosening the bolt 17 and adjusting the screws 19 the bracket may be adjusted inwardly or outwardlyA relatively of the edge of the base.

Inwardly of the bracket and adjacent the forward end thereof I mount a vpivot bolt 21 on which theoffset lug 22 at the end of a lever 23 is mounted. @n the opposite end of the lug I provide an upstanding curved iiange` or head 24, the curvaturel of said flange being concentric to the pivot bolt 21. The lever 23 is bent so as to swing over the foot 15 and forward ear 18. It will be seen that the iange 24- normally stands upon one side of the upright portion of the bracket, while the pivot bolt 21 is on the other side.

One of the important and novel features of the invention resides in an elongated vertical anvil or bending member 25 extending longitudinally of the base and made integraltherewith. That side of the anvil adjacent the bracket is spaced therefrom and is substantially parallel thereto. The forward end of the anvil is reduced gradually in thickness on the outer side so as to produce a comparatively sharp vertical nose or edge 26, which is under-cut so as overhang the lug 22 and stand contiguous to the pivot bolt 21. Between the anvil and the bracket is formed a throat or guideway, which may be varied in width by adjusting the bracket.

The metal bar to be bent is placed on edge in this throat so as to extend forwardly across the lug, with the point at which the bar is to be bent, at the nose 26. The bar will thus be between the nose and the flange 24 of the lever. A piece of pipe or the equivalent 27 may be slipped over the end of the lever to serve .as a handle for swinging the same.. When the lever is swung to the right as seen in Fig. 1 the forward vertical edge thereof swinging in an arc concentric to the pivot point of the lug 22, will exert pressure nearly at right angles to the bar and substantially concentric the nose 26 during the entire bending operation. It will be seen that the flange 24 will bend the bar around the nose 26 to the desired angle, which is determined by making a, marl: in any suitable way. The nose and thel anvil permit ot a sharp bend as well as allowing the bar to be bent` to various acute an les. Y

t will be seen that when the bar is bent, the bent portion is swung over the bench instead of outwardly from the bench, as is the case with the benders uow in common use. The device is so light` in weight that it may be easily carried in a tool kit or itl may be `fastened on the end of a strip of board which is held in one hand; the operator swings the lever 23 with the other hand to bend ceiling bars and the like already in place.

Various changes in the size and shape of the parts as well as modiiications and alterations may be made within the scope of the appended claims.

What I claim, is

1. In a metal bar bending device, a base, an elongated anvil mounted rigidly upon the base and having its entire forward vertical edge reduced to form a comparatively sharp nose, an immovable bracket adjustable on the base with relation to the side of the anvil, a bending lever yhaving an offset lug pivoted on the base directly at the nose of the anvil and an upstanding curved bending iiange on said lever rigid therewith and offset from the lug.

2. In a metal bar bending device, a base, an elongated anvil mounted rigidly upon the base and having its forward end reduced to form a comparatively sharp nose around which a metal bar may be bent at an acute angle, an immovable bracket adjustable laterally on the base withv relation -f to the side o the anvil, a bending lever having a laterally extending lug at its inner end pivoted on the base at the nose of the anvil, and an upstanding flange on the lever offset from the pivot of the lug and adapted to engage a metal bar and bend it around the nose of the anvil.

In testimony whereof I 'affix my signature. Y
